Equipment

  • Large Dutch oven or heavy-bottomed pot
  • Sharp chef’s knife
  • Cutting board
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Blender (countertop blender or immersion blender)
  • Ladle (for serving)

Ingredients
  

  • 2 tbsp butter
  • 1 onion medium and chopped
  • 1 ½ cups celery sliced (about 4 stalks)
  • 3 cloves garlic minced
  • 3 potatoes yellow, peeled and diced (2–3 cups)
  • 6 cups chicken stock
  • 1 cauliflower chopped
  • 1 jalapeño pepper seeded and finely chopped
  • 1 tsp thyme dried
  • 1 tsp sea salt
  • ⅛ tsp black pepper
  • 1 ½ cups cheddar cheese sharp and grated
  • 1 tsp Worcestershire sauce
  • ½ to ¾ cup heavy cream

Instructions
 

Sauté the base

  • Melt butter in a large Dutch oven over medium-high heat. Add onion and celery and cook until softened, about 5–8 minutes. Stir in garlic and cook for 1 minute more.

Simmer the vegetables

  • Add potatoes, chicken stock, cauliflower, jalapeño, thyme, salt, and pepper. Bring to a boil, then reduce heat and simmer (partially covered) for 12–15 minutes, until vegetables are tender.

Blend until smooth

  • Remove from heat. Carefully purée the soup in batches until smooth and creamy.

Add cheese & seasoning

  • Return soup to pot if needed. Stir in cheddar cheese gradually until melted and smooth. Add Worcestershire sauce.

Finish with cream

  • Stir in heavy cream and adjust seasoning to taste.

Serve

  • Ladle into bowls and serve hot. Top with extra cheddar, herbs, bacon or croutons if desired.
  • For the creamiest cauliflower and cheddar soup, always blend the soup while it’s still very hot and work in batches if using a countertop blender. This helps create a silky, restaurant-style texture. Just make sure not to overfill the blender—hot soup expands, and blending in smaller portions prevents spills and ensures a smooth, even purée.

Notes

  • Blending tip: For the creamiest texture, blend the soup in batches while it’s still hot. A countertop blender gives the smoothest result, but an immersion blender works well for a more rustic finish.
  • Cheese matters: Use freshly grated sharp cheddar rather than pre-shredded cheese. It melts more smoothly and gives a richer, less grainy soup.
  • Adjusting thickness: If the soup feels too thick after blending, add a splash more chicken stock or cream until it reaches your desired consistency.
  • Heat level: The jalapeño adds a gentle warmth, not overpowering heat. For a milder soup, remove it completely. For more spice, leave some seeds in.
  • Make it vegetarian: Swap chicken stock for vegetable broth for a fully vegetarian version without losing flavour.
  • Cream swap: Heavy cream adds richness, but half-and-half or whole milk can be used for a lighter option.
  • Flavour boost: Worcestershire sauce deepens the savoury flavour and adds subtle umami—don’t skip it if possible.
  • Make ahead: This soup reheats beautifully. Store in the fridge for up to 3 days and reheat gently on the stove, stirring well.
  • Freezing tip: Freeze without the cream added for best texture. Stir in cream after reheating.
  • Serving idea: Top with extra cheddar, crispy croutons, or a drizzle of cream for a restaurant-style finish.
